My screen brightness using FN+F11/F12 and also in the advanced power settings slider won't adjust the screen to anything other than brightness and minimum or brightness to 100% when I move the slider.  It shows the percentage moving up and down, but the screen stays 100% until I'm on the lowest setting,  then it goes right to minimum.  I received a bunch of Lenovo updates on the first Wednesday of this month and I've had several issues since then, I tried reverting back to previous drivers, but it made no difference, so I'm back on the latest drivers.

Hi, I can't adjust the screen brightness on my X250 at all. I have Windows 7 on it. When I press + and - the slider thing shows up, and it goes up and down, but nothing happens. It's really bright and have already been like this for weeks. The colour is slightly wrong as well. Restarting, shutting down or closing and opening the lid does nothing.It got stuck after I disconnected it from my docking station, so I tried connecting it and disconnecting again - nothing. I've updated Windows and nothing there as well. I'm getting really frustrated since nothing works.. Is there something to do? Please help..

Thank you forum! Much gratitude here for your selfless service!!

I am not very tech savvy but I am usually able to solve my own problems. My cat jumped on my keyboard, my display went dim and I could not adjust it ! I am able to move the brightness bar up and down but nothing happens. First, I tried a system restore but that did not work. I went back about a month which was the earliest restore point I had. Then I went to device driver and looked to see if my driver was functioning properly. I was told it was updated and functioning properly. I tried clicking on the windows generic monitor driver also as advised which did nothing. I went to the device driver on the pc and updated from that which also did not work. I am using windows 10.

Two of the keys on the keyboard are used to adjust the brightness; but, if they are printed in the second color, you may need to hold down the Fn key for them to function. If you can't find them (they look like little suns), I need the model number of the Lenovo to help you more.

So I have read a lot of diffrent ways to solve this problem and I have searched for hours looking for a solution, yet nothing i've tried has worked for me. Whenever i press the fn key and try to adjust brightness then it does't, it does pop up the slider at the corner but it only moves upwards and downwards only one level yet the brightness wont change even that much. I only found one other person that had this problem and he got it solved, but he had an Asus laptop and he got it fixed with some Asus drivers but i have a Dell Vostro laptop. One of the biggest suggestions i have found that has worked for people has been to install some older display drivers, but that hasn't worked for me either.

it's likely you will need to install a utility for that control to work

Hi, I too have a Samsung Monitor (T220) which possibly - like yours - does NOT have the necessary software to link with the 'auto adjust brightness' system within the Charms Menu. You should however be able to adjust brightness (and anything else) via the controls which will I expect be built into the side (or along the base) of your screen.If you haven't already got a copy of your manual you can download a PDF from Samsung which will show how to make the adjustments you require.

I'm not sure if this is in the right forum. But in the last couple months, once in a blue moon I couldn't change my screen brightness, and now in the last couple days it's gotten a whole lot worse. Usually, I can't change brightness either via my 'fn -/+' hotkeys or via the actual brightness slider in the power panel. A full reboot or simple hibernation then reboot both let me change brightness again. But the last couple days, restarting the computer just puts the brightness on either fully dimmed or fully bright, and I still can't change it.

This is an HP G60 laptop, and I've had windows seven for a year on it. Like I said above it only started a couple months ago then got worse this week, and what I've found on google so far was all for newly-updated-to-seven issues. My drivers all seem to be up to date according to the windows update driver function... Can anyone help me?

since a reboot fixes it (at least temp.) it is probably not hardware but software. Do you have a backup from before the problem started getting worse?

Well I've had my laptop for almost 5 months now, however I did break it and got a screen replacement yesterday. Ever since then my screen seems dim. I've altered all the settings (as explained on other threads) but I still can't get to the centre of the problem. I had no trouble altering my brightness before my screen replacement so I do presume that the screen that the shop fitted wasn't the correct one and therefore a cheap option.

What do I do?

A:Screen Brightness won't adjust

Contact the shop that did the replacement, and ask them why it doesn't work now.

I have a new computer , HP recline 23 . OS is win8.1 . It came out of the box with win8 , so I had MS store update to 8.1.

The screen is set very bright , OK for day use but too bright for night use .

My problem is that I can't adjust the screen brightness. After clicking on the charms menu and clicking on settings , the brightness icon is greyed out . It says windows cannot adjust brightness on this computer. I tried the various locations where the brightness slider may be but all the relevant screens show no brightness slider.

I don't know whether win 8 had the brightness control before upgrading to 8.1 ( I mention this because several people complain that after upgrading to 8.1 , they loss brightness control amd regained it by rolling back the driver )

I tried the update driver option but it says my driver is already updated. The roll back option is greyed out
BTW the display adapter shows two adapters : Intel 4600 and Gforce GT730 . How do I check which one is being used?
Any ideas?

Hello.


Please forgive me in advance for some of my spelling / grammar mistakes as English is not really my first language. Even so, I will try to make this post as clear as possible.

So here is my problem. I have an Acer Aspire 4540 laptop that I recently repaired after laying in my closet with a broken display for some time. So I took it to a repair center and got my new 14' LED display installed. Everything on my laptop is working fine, even my screen is working fine. The only issue I've noticed is that when I try to increase or decrease my screen brightness it cycles between the max and min settings rather than dimming or brightening respectively.

Now, I know I've had this issue before but I can't remember if it was already like this before the screen broke. I have tried rolling back, uninstalling and reinstalling my drivers several times yet the issue is still there.

Im running on Windows 7 Ultimate x86 and my graphics card is an ATI Radeon HD4200.

I know this is a small issue but I need to fix it since I spend a lot of time in front of my laptop.


Thanks in advance for your help.

2. If same problem, open the Device Manager > Display Adapters and uninstall the graphics driver (Intel or AMD) and ensure you put a check on Delete the driver software for this device. When finished, navigate to Control Panel (Ivon Views) > Programs and Features and uninstall the Display Driver then reboot. 
 
After the machine has restarted, reinstall the graphics from the B50-70 drivers page or from one of the links below:

Hello,

I've installed Windows 7 on my Qosmio G30-140 but I'm having trouble adjusting the brightness settings.
Instead of allowing me to set the slider to any position I want I'm stuck with only 3 steps from which to choose from.
The last one is way to bright and my eyes keep tearing up from having to deal with this insane amount of white, especially on white backgrounds.
The other two are very, very dark.
What's going on? I've installed the correct Nvidia drivers.
Also I can't seem to set the brightness by using the FN keys on my keyboard. They simply produce no result at all.

First off, I see this seems to be a problem across all of your computers and has been for years... why isn't there a fix? I used my brightness down button once and now it won't go back up. I can't adjust the settings at all, despite the graphic on the screen showing me the meter going up and down. I've checked all drivers, tried uninstalling and reinstalling lenovo energy management, and I've still got nothing. I've stopped short of a factory reset because that's super annoying having set everything up and then a couple weeks after purchase have to do it again. Any other alternatives first? Suggestions?

so as title suggested I want to change brightness of my display of laptop. the battery icon bottom right by clicking on it brings up window's default adjust screen brightness, which is a lot of hassle multiple clicks to get to it.

I have found a few application that could help me change brightness (REAL and ONLY brightness) on multiple monitors at once but its just looks different than window's default brightness change via battery icon. there must be something thats included in window's default brightness change, maybe colors temperature or contrast I do not know which but it isn't only brightness thats changing for sure.

so, could anyone help me and tell me what the differences are? why does it look different and what other things are changed other than just brightness.

also if possible, an application that changes window's default brightness change on multiple monitors at once, which I have yet to find a working one.

It's a shame really, as, I invested loads into this laptop, and, though it's perfectly capable of running Windows 10, the fact that I can't adjust screen brightness wrecks everything. I have even installed the Energy Management driver, but, that doesn't help anything either. Could someone, please, advise me of some way through which I could make Windows simply STAY at the Basic Microsoft Display Adapter driver, or, w...

I recently upgraded to Windows 8.1 on my Lenovo Ideapad and noticed my screen brightness wasn't as bright as it had been when I had run Windows 8. I keep trying to adjust my screen brightness, but no matter how low or high I set it, my screen's brightness
remains at what I would imagine a 50% brightness would be. Can anyone help me?

- then select microsoft basic display adapter

A:How to adjust brightness of HP Omnibook vt6200 display screen

If you have a brightness problem on this laptop, you may have to take it in for service. What operating system (version of Windows) are you running? Have you tried using the Fn key and the "sun" image keys on the top row of the keyboard?
